feat: saas example using Nuxt

[joshua-mo-143]

This version of the SaaS example which uses Nuxt has been kindly provided by @christ-offer, but unfortunately got PRed on the wrong repo. For reference: Nuxt is a front-end web framework that uses Vue as a base - similar to how Next.js uses React as a base.

Once this gets merged I'll delete the extra repo as it seems to be causing some confusion

Comment from me here, the nuxt template is not 100% ready for publishing yet, I have not implemented the modal functionality for single users or single deals, dayjob has taken precedence lately. (Silly me tried to implement it with slugs, which for obv reasons do not work with static SSR).

Also, did you remember to take the new login code from auth.rs and implement it in the Next template, the ok(true)/ok(false) part? (So that it actually checks the password correctly :) )

pub async fn login(
    State(state): State<AppState>,
    jar: PrivateCookieJar,
    Json(login): Json<LoginDetails>,
) -> Result<(PrivateCookieJar, StatusCode), StatusCode> {
    let query = sqlx::query("SELECT * FROM users WHERE email = $1")
        .bind(&login.email)
        .fetch_one(&state.postgres);

    match query.await {
        Ok(res) => {
            match bcrypt::verify(login.password, res.get("password")) {
                Ok(true) => {
                    let session_id = rand::random::<u64>().to_string();

                    sqlx::query("INSERT INTO sessions (session_id, user_id) VALUES ($1, $2) ON CONFLICT (user_id) DO UPDATE SET session_id = EXCLUDED.session_id")
                        .bind(&session_id)
                        .bind(res.get::<i32, _>("id"))
                        .execute(&state.postgres)
                        .await
                        .expect("Couldn't insert session :(");

                    let cookie = Cookie::build("foo", session_id)
                        .secure(true)
                        .same_site(SameSite::Strict)
                        .http_only(true)
                        .path("/")
                        .max_age(Duration::WEEK)
                        .finish();

                    Ok((jar.add(cookie), StatusCode::OK))
                }
                Ok(false) => Err(StatusCode::BAD_REQUEST),  // Password didn't match.
                Err(_) => Err(StatusCode::INTERNAL_SERVER_ERROR),  // Something went wrong while verifying the password.
            }
        }
        Err(_) => Err(StatusCode::BAD_REQUEST),  // Something went wrong while fetching the user.
    }
}

Hey @christ-offer, thanks again for submitting this and apologies it's taken so long to get this merged.

Is there any chance you could re-fork from this repo and then re-add the SaaS example? We'd love to have this as a community example. Unfortunately I accidentally created the extra shuttle-examples repo (see shuttle-examples-1) while doing something else, which means you can't actually edit anything yourself without a PR.
